First, thank you for a nice "casual" (hah!) game that I can keep returning to. But while returning to play your game every few months is *nice*, it's making you no money. Though I note that this game makes an excellent gift for friends :D
So what's next? Please remember to post to these forums when your next project comes out, so we know where else to fling money at.
And preferably even before it comes out, so we can cheer you on and give our usual completely useless suggestions :D
